Divergence of alpine plant populations of three Gentianaceae species in the Qinling sky Island.

ABSTRACT:

Background

Known for their unique biodiversity, the Qinling Mountains are considered the only area in which alpine biomes occur in central China. Given that the alpine biomes are particularly sensitive to global warming, understanding how alpine plants respond to climatic fluctuations is essential for the evolution and conservation of biodiversity. To address this issue, three alpine species of the Gentianaceae (Gentiana crassuloides, G. hexaphylla and Swertia bifolia) that represent different life types and diverse genera were selected.

Results

Genetic clustering analysis according to around 33,317 to 185,133 SNPs showed that the Qinling population was a separate lineage within each species. A high level of genetic differentiation was observed among the Qinling populations
